KAMAZ steps to the alternative energy sources – Sergey Chemezov

KAMAZ has presented a game changing product in the passenger transport segment, the first KAMAZ-6290 hydrogen fuel cell bus, at the COMTRANS-2021 international exhibition in Moscow. KAMAZ continues expanding the model range of innovative passenger eco-transport. Rostec CEO Sergey Chemezov outline this is the next step in the search for alternative energy sources and in the development of modern environmentally friendly passenger transport.

 

“There is still a lot of work to be done. In 2022, we intend to test a prototype KAMAZ hydrogen fuel cell bus in the streets of Moscow, in the environment of actual operation. In case the relevant refueling infrastructure is set up and there is a demand for the new kind of eco-transport on the part of Moscow, we plan to provide for final assembly of hydrogen fuel cell buses at the Sokolniki Car Repair and Construction Plant in the capital of the country, where Kamaz electric buses are already assembled successfully,” Chief Automobile Designer Andrei Savinkov says.

 

Bus chassis and body were assembled at NEFAZ, a company’s subsidiary in Bashkiria. Roof equipment was installed in the research and technology center of KAMAZ. The body is made of high-strength steel and safe plastic, supporting the required durability and safety in emergencies. The total weight of the KAMAZ-6282 hydrogen fuel cell bus is 19 tonnes and its overall dimensions are 12.4х2.55х3.4 m. This innovative product is hydrogen fuel cells-powered and is fitted with six cylinders for compressed hydrogen storage. Cylinders are roof-mounted for safety purposes. Hydrogen flows skyward in case of a leak and does not get into the compartment. Furthermore, unlike the electric bus with the endurance of 70 km after complete battery recharge, the hydrogen fuel cell bus can travel up to 250 km, which makes it applicable even for interurban traffic,” he adds.

 

“The world is moving forward and we cannot lag behind. The hydrogen bus, or the hydrogen electric bus, is the next step in the search for alternative energy sources and in the development of modern environmentally friendly passenger transport. When it was created, the KAMAZ-6282 electric bus was taken as a basis. For three years of use in Moscow, this bus has proven itself well – comfortable, noiselessness with high environmental performance, ” CEO of the State Corporation Rostec, Sergey Chemezov said.

 

The hydrogen power plant capacity is at least 45 kW. The bus is set in motion by ZF electric portal axle. The bus is equipped with the modern high-performance pneumatic braking system with EBS, ABS, ASR, and EPB, slope stop function, motion interlocking function for open doors, and a monitoring sensor for wear and tear of brake pads. Braking by traction electric motor with the regeneration system is also provided. Maximum speed is 80 km/h. Endurance is 250 km. Total passenger capacity is 80, with 33 seats. Like the electric bus, the new eco-transport is adapted to operation at the ambient temperature from -40° to +40°С.

 

“I think the future belongs to hydrogen fuel. I had a chance to test the Aurus on hydrogen fuel – the driving experience is completely different. The car goes absolutely silently, ” Chemezov concluded.

 

Engineers from the KAMAZ Research and Technology Center have tried and made the hydrogen fuel cell bus as comfortable for passengers as possible. A two-zone climatic control system is provided in the compartment, including a separate one for the driver’s cabin. A mechanical ramp is mounted for unobstructed driving of low-mobile citizens into the compartment. Doors can be activated by the passengers themselves. The bus has an electronic passenger address system that can produce an output through destination signs and a display board in the compartment.
